## Technical details

An OS command injection vulnerability exists in Chamilo LMS prior to versions 1.11.38 and 2.0.0-RC.3. The root cause is the improper neutralization of user-controlled input in the move() function within fileManage.lib.php, which passes path values directly to exec() shell commands without using escapeshellarg(). An attacker can exploit this by uploading a directory with shell metacharacters in its name (e.g., via the Course Backup Import feature) and then moving a document into that directory. This triggers the execution of arbitrary commands as the web server user (www-data). While the vulnerability requires authentication, Chamilo's default configuration allows any user to create courses and become a teacher, making the flaw widely accessible. The issue is resolved by implementing proper shell argument escaping or replacing shell-based file operations with native PHP functions.
